摘要
为科学制定森林经营方案,提升森林质量,实现森林可持续经营,基于广西壮族自治区国有博白林场2019年森林资源二类调查数据,运用层次分析法结合模糊综合评价法,从林木生长、森林生产力、林地质量和林分结构构建森林质量评价指标体系,对博白林场森林质量进行评价。结果表明,博白林场森林质量综合指标值为0.404,森林质量处于中等水平;全场森林质量等级良、中、较差和差的小班面积占全场林地面积的比例分别为0.98%、50.62%、48.38%和0.02%,处于中等级的森林面积最大;随森林龄级增加,全场森林质量呈逐渐上升的趋势;除幼龄林外,其余龄组中,混交林的森林质量均高于纯林;除过熟林外,其余龄组中,阔叶纯林的森林质量均高于针叶纯林。
In order to formulate scientific forest management plan,improve forest quality and realize forest sus⁃tainable management,based on ClassⅡsurvey data of forest resources of Guangxi state-owned Bobai forest farm in 2019,forest quality evaluation index system was constructed from tree growth,forest growth capacity,woodland quality and stand structure by analytic hierarchy process and fuzzy comprehensive evaluation method.Forest quality of Guangxi state-owned Bobai forest farm was evaluated.Results showed that comprehensive evaluation index of forest quality in Guangxi state-owned Bobai forest farm was 0.404 and forest quality was at medium level.Areas of subcompartments with good,medium,poor and very poor forest quality grades account⁃ed for 0.98%,50.62%,48.38%and 0.02%of forest area in whole farm,and forest area with medium grade was the largest.Forest quality of whole farm showed a gradual increase with increase of forest age grade.Except for young forests,forest qualities of mixed forests were higher than those of pure forests,and except for over⁃mature forests,forest qualities of broad-leaved pure forests were higher than those of coniferous pure forests.
